Ladies and gentlemen, we have now entered Holkham Bay, named by Captain George Vancouver in 1794. It has two branches, Tracy Arm to the north, and Endicott Arm to the south. “We are heading first into Tracy Arm, which was named by Lieutenant Commander Mansfield of the U.S. Navy, for Benjamin Franklin Tracy, Secretary of the Navy from 1889 to 1893. Mansfield, commander of the survey vessel, Patterson, in Alaska from 1889 to 1913, also named Sawyer Glacier, which you will see at the head of this arm, and which calves the hundreds of icebergs you will see floating in the waters of the arm. This passage was carved centuries ago during an ice age by a massive glacier which completely filled the channel. You can see the signs of its passing in the scoring of the bare rock walls. Avalanche chutes further scar the walls each spring and, as you can already see ahead of us, these are occupied by spectacular waterfalls. We will shortly stop near one of these so you can view it close up and feel how cold the water is coming directly off an unseen glacier at the top. “After visiting Sawyer Glacier, we will go back and turn up Endicott Arm, named for William Endicott, a member of the Massachusetts legislature and the U.S. Senate, to see Dawes Glacier. He was secretary of war from 1885 to 1891. Part way up Endicott Arm we will come to Ford’s Terror, a branch of Endicott Arm which has very strong tidal currents.
